To allwhoniitma concern: Be it known t at ,I, JOHN B. Swan, a citizen of the United States, resldln at Gladstone, in the county of Delta and t tate' l of Michigan, have invented a certain new and usefu Improvement in Sandin Devices for Locomotives,- of which the fol owing 1s a full, clear, concise, 'and .-exact description, reference being had to the accompanying drawings, forming a part of this specificatiom M invention relates-to sanding devices motives'andis concerned with nothe sand-flow;ifi p The sanding of railroad rails from the locomotive 'hss presented quite a 'roblem because of the fact that the end of t e sand pipe or nozzle is necessarily exposedto the weather. The 'sand pipe or nozzle is fre- 'theand; more accurately the freezing of .the nioistureinthefsand, causing it to pack as I 'dn'sed moisture from. the rails and othersources,- such as the steam from the loopmotive, rain-and snow upon the end of the solid and clog itself, and the freezing of consand pipe or noz'zle'with the formation of ice as anobstacle to the flow of the sand.

Devices have been provided in the prior arfiwithfihe intention of eliminating these directing of the sand flow. 1 My inventlon' pmvides an nnproveddedifiiculti'es .butanother difficulty has arisen from ,the fact that the protecting -means often interfered with the most efiicie'nt vice which more eflectively takes care of the protection of the sand pipe or nozzle and' which also rjovides more effectively for the directioni'b the flow than has heretofore been possible.

According to -my invention I providean arrangement wherein the pointof feed of the sandis protected against the elements, wherein the sand pipe end or nozzle is protected as a Whole against cold by static air pockets, and which is of simplified construction.

I shall now-proceed to a detailed descrip tion ofthe preferred form of my invention and shallrefer to the accompanying drawin%, in whichigure 1 is an elevatlon-al view of the proved. meansfor: protecting and directing.

sanding device of my invention disposed-in proximity to the rail and wheel; Fig. 2 is an axial sectional view; and

Fig. 3 is an axial sectional view at right angles to the plane of Fig. 2.

:The device as awhole is in-large part preferably integral and the structure is such as to make a-simple casting, of ironfor instance, possible. The device prqvidesthe actual .feeding nozzle which forms-.an -ex. tension for the sand pipe itself; The feeding nozzle is shown at]. and,- as illustrated, is surrounded by two complete flaring skirts 2 and 3, all three elements extending fronts.

threaded socket adapted to receive -the threaded end of the sand pipe 6, a set screw' 7 being provided to hold the parts-thus joined firmly together. t T 5 It will be-seen that the inner skirt-21s longerxthantlie nozzle 1 and that the outer skirt 3 is'stilllonger, each element having an oblique end and theouter member particularly having its end so formed as tope'imitof close proximity, to the rail and wheel, the top of the rail being indicated by the line 8 and .the wheel being shown at 9."-

The nozzle 1 is of practically uniform formation but the skirts, as stated, flare,

and,-as shown, flare gi'adua'l-ly at first and then more strikingly outward. The flare is greater on its vcrtical'axial plane than on its transverse axial plane and the oblique ends of the three elements permit ready flow of the sandtoward thewheel after it leaves the nozzle and at the "same time prowould have'to bridge. the ap to the inner skirt and then the gap to t e nozzlebefore it could aifect the sand flow from the nozzle, and that is impossible. Moisture to any harmful de ree will not condense primarily head 4 which is provided with a' serew I on the nozz e because it will strike the skirts first, with the result pointed out. 1 Beyond these advantages so far as protection against The transverse cross section flares less as shown to confine the flow against side thrust away from the rail as much as possible.

As a matter of simple and economical structure the skirt 9. is inte ml with the head' t, the outer skirt 3 extem in from and being integral with the inner S(llt-, while the sand pipe end or noz'zle' 1 is screwed into the head. It will also be noted-thatthe nozzle 1 is flattened at its lower end to accord it. to the respective vertical and transverse flares ofthe skirts.

; skirt surrounding said sand pipe and I-claim:

1: In a sanding device, a sand pipe, and a flaring outwardly therefrom, the point of feed being isolated {fromthe edge of said shirt,

. said skirt flaring more in the downward vertical plane than in the other planes, and

theend of saidsand pipe being-flattened to accord thereto, said skirt insulating said sand pipe from moisture and cold.

-Q.In'asandingvdevice, a sand pipe, a

.-- sk'lcrtdsunounding said sand pipe and flarflow the lower end of the sand pipe, the lower,-

,lower end of the sand pipe being the point ing iontwardly therefrom and extending be- 35 low the lower end of the sand pipe, the

of feed and a second skirt surrounding said firstnamed skirt fiaring't-herefrom and extending'below the same.

3. In a sandingdevice, a sand pipe, a skirt surrounding said sand pipe and flaring outwardly therefrom and extending b'eend of.- 't he, sand ipe .being thepoint of feed and-a second s in s'drrounding said first named skirt flaring therefrom. and extending below the same, said skirts flaring more in vertical plane than in transverse p ane.

4. In a sanding device. a sand pipe, a skirt sinrounding said 8:: pipe and flaring outwardly therefrom and extending below the lower end of the sand pipe, the lower end of the sand pipe being the point, of feed and a second skirt surrounding said first named skirt flaring therefrom and extend--' mg below the same, said skirts flaring more in the downward vertical plane than in the other planes and the end of the sand pipe being flattened to accord thereto. 5. In a sanding device, a head providin a socket adapted to thread over the end 0. a sand pipe, a nozzle extending from said head to form an extension from saidpipe, and a skirt extending from said head and surrounding said pipe, said skirt flaring more in the downward directionthan in the other directions.

6. In a sanding device, a head providing a socke adapted to thread over the end of a sand pipe, a nozzle extending fronrsaid head to form an extension from said pipe, and a skirt. extending from said head and surrounding said pipe, said skirt being integral with said head, said skirt flaring more in the downward direct-ion than in the other directions.

7. In a sanding device, a head providing a. socket adapted to thread over the end of a sand pipe, a nozzle extending from said head to form an extension from said pipe,

and a skirt extending from said head and surrounding said pipe, said skirt. being integral with said head and a. second skirt integral with said, first skirt and extending from and surrounding said first skirt, said skirts flaring more in the downward direction than in the other directions.

In witness whereof, I hereunto subscribe my name this 4th day of January, 4. D. 1917,
